Firing pin?

Im fairly new to the gun scene (about a year now), especially when it comes to "fixing" guns.

I have a lakefield mark 3 autoloader that I want to fix myself, as this thing is in hard shape and likely not worth paying big money to fix.

Long story short it misfires a fair bit. Click but no boom. The indent on the round is weak in compairson to the dents left by firing pins of my other .22s so im assuming its my firing pin.

When I manually eject the old round and let the action snap forward the "dud" round always goes off fine, its when the preceding round's energy sets up the next round that I get duds.

Ive cleaned it as best I could given the striped screws that I couldnt get out (I love red rifles...no screwdrivers needed!).

Does this sound like a firing pin problem? How can you tell if a firing pin in a rim fire is on its way out?

thanks guys....
 
I have a Mark III also. I replaced the firing pin and it works great. It sounds more like the action does not recock the way it should when the spent cartridge resets the bolt, leaving a soft strike. I cannot tell what the "stripped " screws are for that you are talking about . If the bolt cannot be taken out and really cleaned, it will stumble and not fire as it should, as there sounds like a bit of crud inside the bolt and housing.
 
I had the same problem and was able to get a new pin from Ellwood Epps. It did not cure the issue 100% but it made it better. It was only after I found a replacement barrel did the problem go away. Look at where the firing pin strikes the top of the barrel (the large cut out) that prevent a dry fire from hitting the bore, if it is worn, your pin may not be travelling far enough to get a full strike.
 
I got it all apart...dirty as heck. Im running hoppes #9 over -everything- and buffing it down with a toothbrush/ running hoppes 9 swabs down the body of the gun (used to have the guts in it).

The screws were striped but it was my lack of know-how too...googled semi auto .22 cals till I found one that looked similar and he striped his...now I know!

Firing pin i think is fine...that is assuming it is supposed to be sloped at a 45o angle to about mid way and then go flat. The flat part is "sharpened" on the sides.

Id put up a photo of my pin but I havnt figured that out yet.
 
Sounds very much like the way the striking surface should be. Mine cycles fine as long as i use long rifle ammo...I tried longs and a mix of the rest but they will not drive the bolt back far enough to recock it.
 
Its all cleaned, oiled, and reassembled. Dying to try it out but Ill have to wait till sunlight :b

Thanks again guys.

UPDATE: works like a new gun, flawless
